Possibility of building a time machine with 可能
Kanji Explanation: Ability and capability with 能

After handing test results to class, the teacher talks about theories of time travel.
- 先生:
- 「タイムマシンを作
( る事( は私( は可能( だと考( えています」- “I believe it is possible to build a time machine.”
- Literal: “As for the matter of making a time machine, I think it is possible.”
- “I believe it is possible to build a time machine.”
Key Points
1可能( = “possible” in a formal, theory-focused sense
- Here, 可能
( だ presents time-machine construction as something the speaker considers feasible, not just imaginable.
2作( る事( は = “as for building one”
- 「タイムマシンを作
( る事( は」 turns the act of building a time machine into the topic of the sentence. - The sentence is not about the machine itself, but about the possibility of the act of making it.
3Ⓐは 可能( だ + と 考( えている
- The core claim is 可能
( だ. - 「と 考
( えています」 softens it into “I think…” rather than stating it as an objective fact.
4Spoken emphasis on topic with repeated は
- The line says 「事
( は 私( は 可能( だ」. - That extra 私
( は is a spoken way to emphasize “as for me, I think it’s possible”.
